Yup those two drains on the front of the car can really cause problems. I am surprised that the car even started.. Usually with enough water in there the battery shorts out. Normally water in the front compartment just takes out the braking system never even thought that it could get sucked from there into the engine in the back.
I personally always worry about water collecting in my intake and getting directly sucked into the engine.

Navy,
Sorry to hear about the misfortune but glad you're covered. However, one unanswered question still sticks in my mind.
How would water get into the fuel lines? Through the evap system possibly? It couldn't have backed up through the injectors. In any case, the gas tank may need to be drained and flushed. I wouldn't risk starting a new motor on water.....

This is a fully stock 996?
Water got into your sealed trunk, past the boot on the sealed master cylinder, and was sucked into the motor via a vacuum booster line - is this right?

No bilge pumps on this ship.
Yes, this is a completely stock 996. The compartment is sealed, however the brake booster draws a vacuum line from the intake manifold and when you fire the engine up and have 3-4 inches of standing water in the compartment, the vacuum line sucks the water in regardless of the boots.
The situation here (as per my mechanic) water in water to booster-water through vacuum line to engine.
Water came in through the intake as too. Apparently there was even H20 in the fuel line. Dont know how that happened though.

I just don't buy this. While I certainly appreciate the dilemma you're facing I can't see one of these cars suffering such a devastating failure from a bunch of water,--and introduced into all those systems?

Make sure you follow the TSB for the brake booster replacement. The have changed seals etc. to help avoid this issue.
You also will want to update your drain tubes (based on your photos) to the ones in the TSB, cost is very minimal for the added protection

I can appreciate doubt, but I think you have to appreciate the amount of water dumped on my car. Caused by a gutter drain without a down spout empting directly onto my car for 3-4 hours.
The hydrolock caused by water in the engine, both through the vacum and the intake damages internal components severely and in this case its most likely a bend rod.

I'm sorry for your loss, and I can't explain the failure, but I'm with Dan; it just sounds like too much of a stretch; the intake air box is full of holes just for this very reason. The box should have been fully drained by the time you started your car.

The major source of water was the vacuum line from the booster, not the intake, though some water came from there too. Again, I don't know about the fuel system. (??).
